In a vertical take-off and landing vehicle, the invention is a method for improving stability by virtue of establishing conversion of thrust vectors over the center of gravity of the vehicle while in the hover position. Through the use of selected angles of inclination of the thrust-generating devices, a positive static stability of the aircraft is maintained. In addition, the spars supporting the thrust-generating devices are mounted in a fixed angular relationship to the centerline of the aircraft\s fuselage, to achieve the desired inclination of the t...
In an aircraft adapted for vertical takeoff and landing, including a plurality of thrust generating elements having an axis of thrust selectively pivotable between a first horizontal thrust generating position and a second vertical thrust generating position, the improvement comprising enhancing in-flight stability of said aircraft in vertical flight by further selectively pivoting the axis of thrust of at least one of said thrust generating elements toward the vehicle center of gravity when said thrust generating element is configured in said vertical t...
